JAY LEWIS, or RUTHERFORDTON, NORTH CAROLINA.

EVAPORATlNG-PAN.

SPECIFICATION forming part of Letters Patent No. 240,738, dated April 26, 1881.

Application filed December 14,1880. (No model.)

To all whom it may concern Be it known that I, JAY W. LEWIS, a citizen of the United States, residing at Rutherfordton, in the county-of Rutherford and State of North Carolina, have invented certain new and useful Improvements i ii Evaporators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereongvhich form a part of this specification.

The present invention relates to that class of evaporating-pans in which provision is made for counteracting the expansion and contraction of the metal bottom, the same being generally attached to wooden side and end boards.

The invention consists in the construction and combination of parts, which will be hereinafter more fully described, and then set forth in the claim.

In the drawings, Figure 1 is a longitudinal sectional view of an evaporatingpan constructed according to my invention. Fig. 2is a perspective view thereof.

The vertical side boards, A, and end boards, B, have attached thereto, by means of nails, screws, or other fastening devices, the sheetmetal bottom (J. The ends of the side boards are extended beyond the end boards, and provided with handles a for moving the pan. The inner sides of theside boards are formed with a series of mortises, which receive the ends of transverse bars D and division-board E. The bars are located in such relation to the bottom of the pan as to leave open spaces between the bottom and the bars for the free circulation or passage of the liquid to be evaporated. The bars are all of the same I height, excepting the one at the upper or feedother side board, so as to enable the same to be adjusted to and from the ends of said crossbars and division -board, for the purpose of counteracting the expansion and contraction of the metal bottom. The adjustment of the side boards. and of the metal bottom secured thereto is accomplished by means of a series of adjusting-screws, G, which work through nu ts H let into the side board, and bear against the ends of the cross-bars and division-board. The outer projecting ends of the adj ustingscrews are made square for the reception of a suitable wrench for turning the same; or they may be provided with heads or wings for the same purpose.

It will readily be perceived that by attach ends of the cross-bars and division-board, so

as to effectually preventthe bottom from warping or bulging.

I am aware that it is not broadly new to construct evaporatingpans of Wooden side and end boards and a metal bottom having screws attached thereto, which serve as means to counteract the expansion and contraction of said bottom.

I am also aware that evaporating-pans have been provided with transverse partition-plates for causing the juice to take a circuitous or zigzag course in its passage through the pan.

I disclaim the devices specified, and confine myself to the construction and combination of parts herein shown, whereby I attain greater simplicity of construction and a more perfect and easy adjustment of the metal bottom.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, i.s
